Ultraman: In the Super-Ancient Era, I Am Dark Tiga

Any Ultraman Stories Set Outside the Ultraman Universe?

For example, there are no Ultramen in a world, but the protagonist obtains an Ultraman transformation device, and monsters begin appearing too.

Any Stories Where the Protagonist Is Dark Tiga and Has a System?

Are There Stories Where the Protagonist Becomes a Brand-New Ultraman Instead of an Existing One?

I mean stories where the protagonist becomes a brand-new Ultraman, not transmigrates into an old one like Tiga, Cosmos, or Zero, and not one of those especially powerful Ultramen either. A completely new one.

Ultraman with a Sound Worldview

I want a protagonist with strong values who doesn't mock, look down on, or disparage other people's dreams. I just read a book where the protagonist was already making fun of someone's dream before I got very far.

Diga Is the Strongest (Dark Tiga)

Books about Ultraman, preferably Ultraman Tiga, with the strongest dark Ultra Warrior.
